Competency Evaluation

Customer experience maturity of any organization is important for its business results. This paper describes two kinds of maturity models, one based on competency evaluation of the employees on customer’s best applied practices, and the second on maturity of using digital tools to increase the customer good experience when working with the company. These approaches are useful when discuss the performance of enterprises providing products or services in the age of customer. The included case studies show the applicability of the procedures and open a way to be extended for proficiency testing workshops (for similar business) or in ranking the enterprises from the viewpoint of customer experience maturity.

Background: Buprenorphine is quite common in the illicit market. Buprenorphine-containing drugs abuse is frequently encountered in patients. The analysis methods used to determine the abuse of buprenorphine and norbuprenorphine are important for forensic science. Buprenorphine is metabolized to norbuprenorphine by the liver. Objective: Therefore, the determination of buprenorphine and norbuprenorphine in urine is one of the methods to determine the abuse of buprenorphine. Methods: In this study, we have developed a precise, simple, and rapid ultra-performance liquid chromatographytandem mass spectrometer method for the determination of buprenorphine and norbuprenorphine simultaneously. Results: The developed method was validated in terms of selectivity and linearity, which was in the range of 9–1800 ng/mL for both buprenorphine and norbuprenorphine. The intra-assay and inter-assay accuracy and precision were found within acceptable limits of the EMA guideline. Lower limits of quantitation were 9 ng/mL for both buprenorphine and norbuprenorphine. Conclusion: The developed method was successfully applied for the determination of both analytes in the proficiency testing samples.
